Better sound for your outdoor TV

Samsung's bright and beautiful "The Terrace" TV was an exciting addition to our outdoor TV lineup. But if you want to enjoy top-notch audio quality to match that stunning 4K QLED picture, we suggest pairing it with this matching HW-LST70T sound bar.

Better sound for your outdoor TV

Samsung's bright and beautiful "The Terrace" TV was an exciting addition to our outdoor TV lineup. But if you want to enjoy top-notch audio quality to match that stunning 4K QLED picture, we suggest pairing it with this matching HW-LST70T sound bar.

Samsung The Terrace TV and sound bar on a patio

Take your movie nights outside with Samsung's "The Terrace" sound bar and TV (sold separately).

Like "The Terrace" TV, the bar is built to withstand extreme temperatures, as well as water and dust. But the bar is also designed and tuned to sound better in those open outdoor spaces, too. Wide-range tweeters and built-in woofers provide a soundstage that is deep and wide, while the dedicated center channel delivers clear dialogue. 

Simple to connect

The HW-LST70T comes with the mounting hardware you need to attach it either to your wall or neatly below "The Terrace" TV. Plus, if you're pairing it with "The Terrace," you won't even need the included optical cable because the two can connect using either Wi-Fi or Bluetooth for a super-clean look.

Easy streaming

When I'm outside, I'm nearly always enjoying some tunes on a portable speaker. Well, there's no need to worry about charging up and toting out your little battery-powered speaker when you've got the HW-LST70T mounted on your porch or patio. It has Bluetooth built in, so you can easily stream music wirelessly from compatible devices.

Product Research



Weather-Resistant (IP55-Rated): The Samsung Terrace Soundbar HW-LST70T is weather-resistant with an IP55-rating. It withstands water, dust, and extreme temperatures.

Note: The soundbar is only water resistant for light water spray; it is not water proof. It should never be completely submerged in water or exposed to heavy water spray.

Optimized Outdoor Sound: The Terrace Soundbar HW-LST70T is tested and tuned at Samsung's California Audio Lab, where their audio engineers apply advanced acoustic technologies and cutting-edge computer modeling to give it optimized outdoor sound. The Terrace Soundbar provides high-quality audio powerful enough for the outdoors and includes a center channel (3.0CH) for crystal clear dialogue.

3.0 Discrete Channels: The HW-LST70T is a 3-channel soundbar with dedicated left, right, and center channels that can provide virtual surround sound. With a center channel dedicated for the sole purpose of delivering clear dialog, you'll never miss a word of your movie soundtrack. The soundbar consists of seven total drivers; each front left and right channels consists of a single cone woofer and one soft-dome tweeter, while the center channel includes two cone woofers and one wide-range tweeter. The soundbar is powered by a built-in 210 watt amplifier that delivers 45 watts to each woofer and 10 watts to each tweeter.

Sound Technologies: The Terrace Soundbar HW-LST70T utilizes unique Samsung audio technologies to provide you with the best outdoor sound.

  • Q-Symphony: Q-Sympphony synchronizes the Samsung Terrace Outdoor TV speakers with the HW-LST70T soundbar speakers for fuller, more immersive, cinematic sound. This feature requires an optical digital connection (not compatible with WiFi or Bluetooth).
  • Adaptive Sound: The Terrace Soundbar analyzes your audio content to automatically deliver optimized sound based on each scene, letting you hear speech clearly at the lowest volumes.
  • Distortion Cancelling: Distortion Cancelling technology reduces distortion before it happens, for deep bass and dynamic audio.

Sound Modes: You can select between two Sound modes - Surround or Standard.

  • Surround: The Surround mode delivers a more realistic and immersive audio experience by adding depth and spaciousness to the movie soundtrack. From nearly any corner of the room, Surround blankets the listening area both sideways and up to screen level for a more immersive surround effect.
  • Standard: Select Standard mode if you simply want to enjoy 2ch stereo playback.

Audio Settings: The Samsung HW-LST70T outdoor soundbar provides several audio adjustments to customize your listening experience.

  • Bass & Treble: You can independently adjust the bass & trebel level of the outdoor soundbar speaker from -6 to +6 to tailor the sound to your preference.
  • AV Sync: AV Sync can be used to help sync video to audio when connected to a TV. Video may look slower than the audio if it is connected to a digital TV. If this occurs, you can adjust the audio delay time to match the video. You can adjust the AV Sync from 0 to 300ms.

Mounting Options: The HW-LST70T outdoor soundbar comes with a mounting kit that allows it to mount directly to the Samsung Terrace outdoor television. It can also be mounted directly to a wall for use with other outdoor televisions.

Note: This soundbar is not designed to be placed on a tabletop, shelf, or piece of furniture. It must be mounted to a compatible Samsung Terrace outdoor television or mounted directly to a wall.


Optical Digital Input: The Samsung Terrace Soundbar is equipped with an optical (toslink) digital input to connect your television. The optical digital input is hidden and protected by a removable cover on the back of the soundbar. The optical digital input supports Dolby Digital (5.1ch), DTS (5.1ch), and 2Ch PCM. The optical digital output of some flat-panel TVs only send a Dolby Digital audio signal when receiving Dolby Digital surround sound from the TV's built-in tuner, network connection, or connected USB device; and will output only 2ch PCM from sources connected to the TV via HDMI, or RCA (like your Blue-ray/DVD player or satellite/cable box).

Note: This soundbar is not equipped with a HDMI or analog input.

Built-in Bluetooth: The Samsung HW-LST70T features built-in Bluetooth 4.1 for wireless connection between the soundbar speaker system and your Bluetooth-enabled mobile devices for wireless music streaming, as well as a wireless connection between the soundbar speaker and Bluetooth A2DP enabled TVs.

The HW-LST70T does not display song/artist information (song/artist info is still viewed on your Bluetooth source device).
  • Wireless TV Connection: You can simplify the installation of the HW-LST70T by eliminating the need for a wired connection between a Bluetooth-enabled TV and the soundbar. Simply plug the soundbar and the subwoofer into AC power and follow the simple pairing instructions to wirelessly connect the soundbar to a Bluetooth A2DP enabled TV. When a TV is connected using Bluetooth, audio is transmitted in stereo (not Dolby Digital or DTS). Only one TV can be paired and connected at a time.


  • This system does not support Bluetooth hands-free communication for phone calls.
  • Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Samsung HW-LST70T.

You can also upload your personal music collection from iTunes, Google Play Music, and more to your music library on Amazon and then stream your music through the Samsung soundbar system.

Yes it does and it's awesome we use airplay / Sonos to distribute sound to 9 zones. One thing if you have both the soundbar and the tv speakers the sound is really big.

Is this designed to be outside all year (midwest)? Looking to mount it on my Pergola
sal  Aug 24, 2021
2 answers
I purchased this one because the specs indicated year around outdoor use. Ours is mounted in a pergola too. If weight is any indication of its outdoor construction then it gets high marks.easily 3x heavier than our inside-use Bose model of similar size.
robert  Aug 26, 2021
Will it be covered from direct rain, snow, and sun? If so, I would not.
javier  Aug 24, 2021
